CIS-MPPT 75/20
With innovative maximum power tracking technology, this Phocos MPP tracker ensures maximum performance and yield from all types of solar systems – year-round, in any weather, and in any environment.
The use of MPPT technology can contribute to a considerable boost in energy output from PV modules (up to 30% more). At the same time, the temperature-compensated, three-stage I-U curve charge control algorithm significantly extends battery lifespan.
The integrated data logger provides an insight into system operation, displaying important information such as system status, voltage, current, etc.
Thanks to the maximum power point technology, lower cost modules, intended for grid connected applications (up to 75 V open circuit voltage), can now be used resulting in attractive system cost savings.
